Subject: [PATCH 12/17] clocksource: Add Kconfig entries for CMT, MTU2, TMU and STI

From: Magnus Damm <damm@...nsource.se>

Add Kconfig entries for CMT, MTU2, TMU and STI to
drivers/clocksource/Kconfig. This will allow us to
get rid of duplicated entires in architecture code
such as arch/sh and arch/arm/mach-shmobile.
